Lower IQ Linked to Higher Risk of Heart Deaths 

“Intelligence appears to be one reason why poor people are more likely to die of cardiovascular disease, Scottish researchers say. They analyzed data on 4,289 former U.S. soldiers, and found that IQ accounted for more than 20 percent of the difference in heart disease and stroke deaths between people of high and low socioeconomic status. This was in addition to well-established cardiovascular disease risk factors such as obesity and smoking. The study appears in the July 15 issue of the European Heart Journal. ‘We already know that socioeconomically disadvantaged people have worse health and tend to die earlier from conditions such as heart disease, cancer and accidents,’ study leader Dr. David Batty, an epidemiologist at the Medical Research Council's Social and Public Health Sciences Unit, University of Glasgow, said in a news release.
